Title says most of it. So basically I want to hang up a hanging hammock onto this lattice like structure we have attached to our roof (and to concrete pillars in the ground). How in the hell do I tell if this is safe both structurally (as in I won’t damage the structure), but also for me (as in it won’t collapse and hurt me).

The close up picture is where the wood is connected to the concrete pillars.
